Ala-D-γ-Glu-Lys-D-Ala-D-Ala is the pentapeptide tail of the peptidoglycan precursor UDPMurNAc-l-Ala-γ-d-Glu-l-Lys(Gly)(5)-d-Ala-d-Ala. Ala-D-γ-Glu-Lys-D-Ala-D-Ala is used to study the role of this peptide stem in peptidoglycan biosynthesis, degradation and function.
Biochem/physiol Actions
L-Ala-D-Glu-gamma-L-Lys-D-Ala-D-Ala, peptidoglycan pentapeptide, is the antigenic peptide determinant of peptidoglycan useful in studies of mechanisms of action of glycopeptide antibiotics.
The Biochemical journal, 123(5), 789-803 (1971-08-01)
Vancomycin forms complexes with peptides terminating in d-alanyl-d-alanine that are analogous to the biosynthetic precursors of bacterial mucopeptides. The specificity of complex-formation has been studied by means of many synthetic peptides, prepared by both solid-phase and conventional methods. The following
Immunochemistry of a synthetic peptidoglycan-precursor pentapeptide.
The Journal of experimental medicine, 138(5), 1184-1193 (1973-11-01)
The relationship between 7S anti-IgG and antibodies to streptococcal cell wall peptidoglycan was examined for four streptococcal Group C antisera. Homogeneous 7S anti-IgG components in these sera were isolated by means of an IgG immunoadsorbent column. For two of the

Staphylococcus epidermidis peptidoglycans solubilized by sonication or lysozyme digestion, and synthetic peptidoglycan analogs such as HSA-carboxymethyl-Gly-L-Ala-L-Ala-D-Ala-D-Ala (HSA-pentapeptide) or L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala (pentapeptide) have been labeled with 125I and tested for their applicability in the radioactive antigen binding assay. Use of radioiodinated Staph.
Journal of immunology (Baltimore, Md. : 1950), 117(1), 23-26 (1976-07-01)
A radioimmunoassay has been developed for the measurement of antibodies to peptidoglycan in human sera including patients with rheumatic fever and juvenile rheumatoid arthritis. The assay is based on the percentage of binding of the hapten 125I-L-Ala-gamma-d-Glu-L-Lys-D-Ala-D-Ala, the major peptide
